Game Score using FIP

By Tangotiger, 02:53 PM

No, I’m not talking about this recent BtB article, which does some good work.

I am instead talking about this article that came out a few months after the unveiling of FIP 5 years ago, back when DIPS was all the rage, and he shows you all his work:

What would a DIPS-based game score look like?  Also, why not make the revised game score equivalent to a support neutral win probability?  ... GSDIPS = 50 + IP + 2*K – 3*BB – 13*HR

And there you have it – a DIPS-based pitcher game score equivalent to support neutral win probability that is easier to calculate and with fewer terms than James’ original Game Score!

Notes:  Did James originally intend the Game Score to approximate win probability?  The (2*K – 3*BB – 13*HR) term is the same thing as FIPS that was independently and originally noted by TangoTiger as a DIPS-based pitcher measure

Kevin’s got alot of other great stuff on his site.  I get the feeling that alot of the new guys coming into sabermetrics aren’t aware of the really cool stuff that’s already been done out there.
